Brax MX4

Based on our basic principles “handmade” and “made in Germany” we have designed the amplifier BRAX MX4 according to the latest technical knowledge. The result is both a top-class amplifier and a true high-end statement: A long lasting period of research and development, innovative technologies and an extremely fastidious manufacturing combined with the love for music as the driving force for our work make the BRAX MX4 doubtlessly to the most powerful and best sounding 4-channel amplifier of the world.Concerning the straight design of the MX4-amplifier and the sophisticated layout of the circuit board, we have deliberately set crossovers and filter functions aside. Short signal paths combined with selected components “made in Germany” ensure pristine listening pleasure and underline the puristical high-end philosophy of the BRAX MX4.In order to completely eliminate power differences and manufacturing tolerances, we only use hand-selected transistors for the production of each MX4-amplifier. Concerning power-, voltage- and resistance data we select them in more than 300 categories. Thus, all transistors harmonize perfectly in terms of technical specifications. In doing so, our BRAX amplifiers obtain a worldwide reference status. Striving for ultimate perfection, Audiotec Fischer is the only manufacturer of audiophile products on the globe that conducts this extensive and time-consuming hand-selection. Of course, all the instruments that are necessary for this procedure are in-house developments.Two separate power supplies for the channels A/B and C/D account for an endlessly stable power output. The amplifier’s output is even stable when you connect loudspeakers and a woofer with different impedances to the BRAX MX4. In order to control voltage fluctuations, an external power stabilizer can directly be connected to the power supply. Moreover, the solid and gold-plated terminals for cables up to 50mm² make another contribution to an ideal power supply of the BRAX MX4.At the end of the day, the BRAX MX4 can be described as an amplifier with a sound rendition that is highly dynamic, powerful in an awsome way and swift as an arrow. The underlying philosophy is topped-off by a packaging in a precious wooden box. Furthermore, each single amplifier is manufactured individually and its respective serial number is recorded in our data-base. The amplifier BRAX MX4 is only produced on demand and of course we can respond to our customer’s requirements. In this way, each amplifier is a valuable individual item that rightly deserves the title “high-end made in Germany”.Optical digital inputs used for the upcoming BRAX DSP (2 x Toslink)Separate terminal for connecting a BRAX Power Stabilizer directly to the switching transistorsEight capacitors (with a total capacity of 40.000 microFarad) take care of an extremly high current impulse load200 Ampere high-performance switching transistorsInterference-free power supply due to optimized suppression coil up to 300 Ampere with ultra-low internal resistanceEspecially developed transformers with highly-efficient core materials guarantee a total performance of more than 1.800 WattsHigh efficiency due to super-fast Schottky power diodes with more than 160 Ampere in totalBelow the lateral PC-boards there are in total 32 hand-selected high-end MOS-FET transistors which account for brilliant soundProcessor controlled operating data management of the amplifier and power supply.
